C is the correct answer
(x - 6) (x - 6) = x^2 - 6x - 6x + 36
= x ^2 -12x + 36
Answer: x=-8
Step-by-step explanation: 12-5x+6x=4 1. Combine like terms: -5x+6x+12=4 2. Simplify: x+12-12=4-12 3. Subtract 4 from -12 so that you can find out what x is: x=-8
Each flow element requires a test gauge ---> 32*80 = $2560
Each flow element needs total of 6 feet of tubing ----> 32*6 = 192 ft
price per foot = 6/100 = $.06
-----> 192*.06 = $11.52
Each 3-ft length of tubing requires 2 connectors. ----> (192/3)*2 = 128
-----> 128*2.5 = $320
Total Cost = 2560 + 11.52 + 320 = $2891.52
Subtract from budget:
3000 - 2891.52 = $108.48
